摘要： The invention relates to electronic badges equipping portable objects, such as plastified cards and capable of being identified at a distance by suitable readers in order to ensure operation such as the unlocking of a lock. These badges are of a passive type, that is to say supplied exclusively from the outside by inductive coupling and they are in addition of a type reprogrammable through channels, each comprising an inductive coupling (at the level of inductances) from a suitable apparatus. The circuitry for forming the binary coded identification signals of the badge comprise a dead memory, a life memory or buffer and a rapid reading and writing circuit which provides the connections between these two memories, as well as the connections between the dead memories and the reprogramming channels.
